Level: Kineticist 9
|

|
|
Manifesting Time: 1 round
|
|||
|
|
Range: Long (400 ft. + 40 ft./level)
|
|||
|
|
Area: 40-ft.-radius spread
|
|||
|
|
Duration: Instantaneous
|
|||
|
|
Saving Throw: Reflex half; see text
|

|
Power Resistance: No
|

Power Points: 17

Metapsionics: Empower, Maximize, Twin, Widen

You induce the formation of a slender vortex of fiercely swirling air. When
|
|||
|
|
you manifest it, a vortex of air visibly and audibly snakes out from your
|
|||
|
|
outstretched hand.
|
|||
|
|
|
|||
|
|
If you want to aim the vortex at a specific creature, you can make a ranged
|
|||
|
|
touch attack to strike the creature. If you succeed, direct contact with the
|
|||
|
|
vortex deals 8d6 points of damage to the creature (no save).
|
|||
|
|
|
|||
|
|
Regardless of whether your ranged touch attack hits (and even if you forgo
|
|||
|
|
the attack), all creatures in the area (including the one possibly damaged
|
|||
|
|
by direct contact) are picked up and violently dashed about, dealing 17d6
|
|||
|
|
points of damage to each one. Creatures that make a successful Reflex save
|
|||
|
|
take half damage.
|
|||
|
|
|
|||
|
|
After being dashed about, each creature that was affected finds itself
|
|||
|
|
situated in a new space 1d4 x 10 feet away from its original space in a
|
|||
|
|
random direction. Walls and other barriers can restrict this relocation; in
|
|||
|
|
such a case, the creature ends up adjacent to the barrier.
|
|||
|
|
|
|||
|
|
Augment: For every additional power point you spend, this power<65>s area
|
|||
|
|
damage (not the damage from direct contact dealt to a specific
|
|||
|
|
creature) increases by 1d6 points. For each extra 2d6 points of
|
|||
|
|
damage, this power<65>s save DC increases by 1.
